I’m new to 3D modeling (so please bear with me if I’m dumb), but I wanted to have something (a sword hilt) 3D printed, so I took a free model from online and imported it as an STL file, and then modified it for my purposes.
I sent the piece out to be printed professionally, and they sent me this response:
“I am guessing that you built one side of this handle in a half and then mirrored it? When that was done, I do not think you united/joined the two halves to be one solid body. When this happens, a gap between halves is sometimes created and the part will not print correctly. Please go back and ensure this part is one solid body.”
I never mirrored anything, so I’m guessing that the problem must be an underlying one in the model I used, however, since I imported it from an STL file, the original model all shows up as one object, and a join mesh operation doesn’t do anything.
Is there some other operation that I don’t know about that would work, or would I need the original design file in order to fix this problem?
Thanks in advance for any helpful advice.
